Install .NET 8

Installing 💿 .NET 8 on Ubuntu 24.04 takes just two commands in your terminal. You update your package list first to make sure your system has the latest software details, then run the installation command to set up the software development kit on your machine.

Run the command below to install .NET 8 on Ubuntu.

sudo apt update
sudo apt install dotnet8

Once installed, run the command below to verify the .NET version number.

dotnet --version

Create Hello World app

Creating a Hello World app lets you test your .NET 8 installation on Ubuntu 24.04 to make sure everything works properly. You use the built-in dotnet command to generate a new console project, which creates a basic template you can run right away.

Run the command below to create a simple Hello World app.

dotnet new console -o helloworld

Change into the helloworld folder and run the app.

cd helloworld
dotnet run

It should output [Hello World] on your terminal.

Creating an ASP.NET app is also possible. To do that, run the command below.

dotnet new razor -o asp.net

Change into the [asp.net] folder and run the app.

cd asp.net
dotnet run --urls=http://0.0.0.0:5000/

To test, open your browser and navigate to the server hostname or IP address followed by port number 5000.

http://srv1.example.com:5000

That completes the setup process.
